Back in the seventies load switches, sulfur hexafluoride switches and vacuum switches competition in general there have been a fierce factional great debate in the international market. Proposed vacuum switch sulfur hexafluoride send a strong X-ray will be breaking current process, seriously endangering the health of the operator load switch wholesale, and should be a total ban on use. And sulfur hexafluoride gas has excellent arc performance and insulation performance, no - kind of media or mixed media to replace it. Vacuum after school is considered by the breaking of sulfur hexafluoride gas electric current in solitary combustion load switch, immediately break down into toxic gas, sulfur hexafluoride switch box in every moment from leaking into the atmosphere trace, the leakage the total is very impressive, especially when sulfur hexafluoride switch explode undoubtedly more serious. If widely used sulfur hexafluoride gas as a switch arc medium, atmospheric pollution is out of control. Debate on the vacuum pressure to send very large load switch factory outlets, the school conducted a number of breaking current measurement, fortunately measure X-ray radiation is much lower than the number of measurement standards and concluded that the hazard to the operator. This great debate finally reported at the time of a paragraph. Sort by using the voltage load switch can be divided into high-voltage and low-voltage load switch load switch load switch, load switch Hohhot, Xi'an by the Xi'an high Huayi power plant. Xian Huayi Electric Power Equipment Factory (www.xahy.com) strong, credible, in the Xi'an high-voltage circuit breakers and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi electricity into the brilliant and you work for a better future!
